So I have this encrusting montipora frag, that I've had for almost 3 months now. It keeps getting white spots in the tissue. At first I thought my blue tang was nipping at it. Blue tang has since been moved to a different tank.

The only fish still in with this frag is a kole tang and a lawnmower blenny plus an urchin.

I have never seen a fish nip at this montipora. I've also never been able to see any pests on it.

Is this signs of a montipora eating nudibranch?

Would I need to pull the frag out to see the nudibranch or would it be visible just by looking from outside the tank?

Nudis are visible at night mostly. I kinda think your urchin is eating along the edges trying to get the algae.

That crossed my mind as well but the urchin usually stays near the back of the tank. But I also noticed there isn't a trail in the coraline algae that it eats leading to the frag.

So I also started to notice that some of my coraline algae is turning white. Maybe that's in relation to the problem with the montipora. Calcium is a lower than what I usually keep it at.
Calcium is 375, I usually keep it around 425.
DKH is 8.1
Magnesium is 1480.
